O estudo busca fazer uma aproximação entre a Sociologia da Educação e as Tecnologias da Informação e Comunicação. O objetivo do trabalho é compreender as relações desenvolvidas no interior das instituições escolares com esses dispositivos móveis de conexão a internet. As práticas, os significados e os questionamentos existentes nesse fenômeno contribui para a reflexão sobre o espaço escolar inserido na Sociedade da Informação. A leitura do campo através do conceito de experiência social de François Dubet indica trabalho de autoria exercido pelos atores escolares frente as normas institucionais que organizam os fazeres educativos. A metodologia de investigação utilizou-se da observação participante e da aplicação de questionários com educadores e educandos para aprofundar o entendimento do objeto de estudo. A análise de dados identificou a existência de mediações entre as demandas estudantis e as exigências institucionais veiculadas pelos professos no regramento das posturas em sala de aula. É possível concluir que a dimensão comunicativa da escola deve ser valorizada, sendo necessário experimentar práticas escolares onde os recursos multimídias do celular estejam articulados em projeto educativo de forma a integrar diferentes linguagens na construção dos conhecimentos. / This research is a study about the use of cellphones in Human Science’s class, analyzed on two high schools maintained by State. The investigation explores interfaces between Sociology of Education and Tecnology of Information and Comunication. The point of search is realize about developing relationships in schools with cellphones and learning. Understant how pratices, meanings and questions in this phenomenon contributed for thinking educational spaces in Information Society. The concept of social expirencie formulated by François Dubet produced interpretations of field work in which demonstrated authorship in educational institutions. The metodology work was used participant observation and survey with students and teachers for collect information related to the object of study. The date analysis identified mediations between student's needs and institucional's script in class behavior. It's a possible conclusion the neccessity to valorize communicative and interactive dimension in school from experimenting multimedia resources of cellphone. This experiences should contribute for articulate an educational project with different languages to building knowledge.

Many organizations now realize the important role of social network technology (SNT) in building social capital and hence broadening their customer base. However, observations have indicated that, while working, many knowledge workers use SNT to engage in non-job related activities, potentially leading to a decrease in productivity. The purpose of this study was to examine the relationship between the usage of SNT and productivity in the health sector. The theoretical foundation of this study emanated from Rogers's theory of diffusion of innovations and Campbell, Rodney, Scott, and Christopher's theory of performance. Collection of data involved a self-administered survey designed with tools from SurveyMonkey. Out of 123 respondents, some were team members (67%), some were independent (24%), others were team leaders (8%), and a few were administrators (2%). A multiple linear regression analysis subsequent to correlation analysis between each of the 4 variables of SNT (frequency of SNT use, duration of cellphone-based SNT use, duration of PC-based SNT use, and performance rating) and knowledge worker productivity revealed a significant relationship between productivity and performance. The findings suggest that, of the 4 SNT variables, performance rating statistically predicts productivity of the health care professional. Managers may find these results informative in their effort to boost productivity among their health care professional workers. Further investigations are recommended to explore the association between productivity and SNT among knowledge workers.

O desenvolvimento técnico da eletrônica, a contínua redução do tamanho dos receptores GNSS, associada à diminuição do consumo de energia, transformaram estes produtos em alguns circuitos integrados ou apenas pequenos chips do tamanho de um botão de uma camisa. Desta forma pode-se promover a sua integração com inúmeros dispositivos eletrônicos. A associação com os telefones celulares foi principalmente impulsionada pelo mandato de aprimoramento dos serviços 911 (E911) da Federal Communications Commission (FCC) nos Estados Unidos, exigindo que todas as operadoras de telefonia móvel daquele país fornecessem a localização com boa precisão das chamadas de emergência. Esta necessidade estimulou a produção dos chips em larga escala e, portanto, a diminuição do custo e a sua popularização. Desta maneira quase que em sua totalidade, os telefones celulares são hoje fabricados com receptores GPS, o que torna estes dispositivos uma das fontes mais baratas de se obter o Geoposicionamento. Acontece que existe uma lacuna na literatura quanto à precisão e a exatidão das coordenadas fornecidas por estes equipamentos. O presente trabalho visa, através de testes estatísticos e da comparação com outros receptores GPS e métodos, quantificar estes valores e propor uma metodologia para melhorar tal posicionamento. Para conseguir o objetivo, a estrutura do Sistema Operacional do telefone foi modificada de tal modo que fosse possível o acesso às observáveis do chipset do GPS embarcado e convertidos para o padrão RINEX de arquivamento de dados brutos. Os testes foram executados com o equipamento original e com o equipamento modificado com a instalação de uma antena externa e mostraram que com a utilização da medida de fase da portadora o equipamento pode fornecer o posicionamento com uma precisão média de 0,069m, com o desvio padrão de 0,047m e erro planimétrico de posicionamento máximo de 0,218m e mínimo de 0,004m. / The technical development of electronics, the continuous reduction in the size of GNSS receptors, allied with the energy consumption decrease, transformed these products into some integrated circuits or in small Chips as small as size of a button of a shirt. In this way one can promote its integration with countless electronic devices. The association with cell phones was mainly driven by the mandate to enhance services 911 (E911) of the Federal Communications Commission (FCC) in the United States, requiring that all mobile carriers of that country provide all the emergency calls location with good accuracy. So as to fulfill this necessity, the production of Chips in a large scale has been stimulated and therefore the decrease in cost and its popularity. In this way almost in its entirety, cell phones are now manufactured with GPS receivers, which makes these devices one of the cheapest sources to obtain the geopositioning. It turns out that there is a gap in the literature about how precise and accurate the coordinates provided by these equipments can be. This thesis aims through statistical tests and comparison with other GPS receivers and methods, quantify these values and propose a methodology to improve such positioning. To achieve the objective, the structure of the phone\'s operating system was modified in such a way that it was possible to access the embedded GPS Chipset observables and then converted into the RINEX standard raw data file. The tests were carried out with the original equipment and with the modified ones, with an external antenna installation which showed that using the phase measure of the carrier, the equipment can provide a positioning with an average accuracy of 0, 069m, with a default deviation of 0, 047m and a maximum planimetric positioning error of 0, 218m and a minimum of 0, 004m.

Thesis (MSc)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: This thesis investigate the di erent available GSM bearer channels that can be used to launch a cellphone banking application. Speci c attention is given to launch such a cellphone banking application to the so called \bottom of the pyramid". In South Africa, there are an estimate 11 to 13 million people with no bank accounts. The cellphone create an ideal opportunity to be used as a tool to reach this untapped market segment that today mainly uses cash to pay for day to day living expenses. The thesis provide more information on the cellphone banking arena in South Africa as well as certain projects in other parts of the world. The thesis also highlight new devel- opments on cellphone technology that include Android and IPhone delivery channels. Focus is placed on how the cellphone banking presentation layer must be delivered through the USSD GSM bearer channel. USSD is at the current moment the ultimate channel to consider due to its extensive reach and ability to work on any GSM cellphone handset. In conclusion, although cellphone banking can be used by any person, the bene t to bring nancial services to the bottom end of the pyramid must be considered to achieve nancial inclusion. The cellphone due to its reach is the ideal medium to access this lower end market. / AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek beskikbare GSM selfoon kanale wat gebruik kan word om 'n selfoon bankdienste toepassing te initieer. Spesi eke aandag word gegee om so 'n selfoon bankdienste toepassing uit te rol na die sogenaamde onderste gedeelte van die bevolkings piramiede. Die tesis verskaf meer informasie oor die selfoon bankdienste arena in Suid Africa maar dit brei ook ooit oor sekere soortgelyke projekte in ander dele van die wereld. Die tesis lig ook nuwe ontwikkelings uit in selfoon tegnologie wat Android en IPhone mediums insluit. Fokus word geplaas op die selfoon bankdienste vertoning deur die USSD GSM kanaal. USSD is huidiglik die beste kanaal om te oorweeg as gevolg van die wydverspreide beskik- baarheid omdat die tegnologie op enige selfoon handstuk werk. Die uiteindelike gevolgtrekking uit die werkstuk is dat selfoon bankdienste deur enige persoon gebruik kan word, maar selfoon bankdienste is 'n goeie idee om te oorweeg om mense in te sluit uit die onderste gedeelte van die bevolkings piramiede. Die selfoon kan dus as 'n ideale medium gebruik word om hierdie mense te betrek by nansiele dienste.

Para isso, discutem-se as principais características e dificuldades encontradas, por esses dois setores, na tentativa de implementação e gerenciamento de um modelo de negócios adequado à Indústria de Entretenimento Móvel. Realizou-se uma pesquisa exploratória, qualitativa, na qual foram efetuadas entrevistas com representantes da telefonia móvel e fornecedores de conteúdo de entretenimento no Brasil. Também foram analisados documentos secundários, tais como dados dos dois setores investigados disponíveis em websites e reportagens em revistas de negócios. Observou-se que, devido a uma relativa saturação do mercado de voz, o setor de telefonia celular, no Brasil, vem tentando ampliar suas receitas, direcionando-se para produtos da indústria do entretenimento. Essa junção vem resultando em um tipo novo de indústria. O avanço tecnológico foi determinante para essa interação através da evolução dos telefones celulares, que incorporaram novos recursos multimídia transformando-se numa nova mídia, com o surgimento do protocolo de Internet (TCP/IP). Com a tecnologia disponível, as duas indústrias começaram a ter interesses recíprocos: a indústria de telefonia móvel buscando oferecer novos serviços a seus usuários, visando o aumento do ARPU (Average Revenue per User); e a indústria de entretenimento buscando uma nova mídia para vender seus produtos, principalmente jogos, músicas e vídeos digitais. Entretanto, essas indústrias se posicionaram em bases diferentes, apesar de serem indústrias de serviços: a indústria de telefonia móvel, no Brasil, tem sua base na venda de mercadorias comoditizadas, tanto com minutos de voz quanto pela troca de dados; já a indústria do entretenimento tem o valor imaterial e intangível muito forte na composição do preço de troca de seus produtos. As diferentes formas de fazer negócios dessas duas indústrias têm gerado dificuldades na solidificação do que se convencionou chamar, no ambiente mercadológico, por “modelo de negócios”. 9 O desenvolvimento de modelos de negócios que responda às necessidades das duas indústrias é, segundo os entrevistados, o principal obstáculo para o aproveitamento do potencial da Indústria de Entretenimento Móvel. Essas diferenças constituem-se no principal argumento, deste autor para considerar a Indústria de Entretenimento Móvel separada de suas indústrias formadoras, criando uma 'nova indústria'. / In this dissertation it’s presented the current stage of the Mobile Entertainment Industry in Brazil, based on an analysis of Mobile Phone Industry and its interaction with Entertainment Industry. Thereto, it’s discussed main characteristics and difficulties found, by these two industries, trying to implement and manage a feasible business model for MEI. It’s been carried out an exploratory qualitative research when Brazilian mobile phone and entertainment content providers representatives were interviewed. Secondary documents were also analyzed – as data for the two investigated industries available in websites and business magazines articles. It was observed that, due to relative voice market saturation, the Mobile Phone Industry, in Brazil, is trying to increase its revenue, focusing on Entertainment Industry products. This merge is resulting in a new type of industry. Technology development was crucial for this interaction with technology evolution of mobile phones, incorporating multimedia features, turning itself into a new media, with the emergence of the Internet Protocol (TCP/IP). With the available technology, the two industries began to show mutual interest: the Mobile Phone Industry searching for new services to its users, looking for ARPU (Average Revenue per User) enhancements; and Entertainment Industry in quest of a new media to sell its products, specially games, digital music and videos. However, these two industries has positioned themselves into different bases, despite of been service industries: Mobile Phone Industry in Brazil, has based its revenue in the merchandise of commodities, as voice minutes or data exchange; yet, the Entertainment Industry has immaterial and intangible value strongly influencing the price of their products. However, different ways of doing business of these two industries are causing difficulties in the solidification of what is uselly called, in the business environment, “business model”. The development of business models that respond to the needs of the two forming industries are, according to the interviews, the main obstacle for the full potential employment of the Mobile Entertainment Industry. These differences comprise the main argument, of this author, to consider Mobile Entertainment Industry separated from its constitutive industries, generating it a ‘new industry’.

This dissertation describes research which investigated the use of communication tools in a WebCT learning environment. The instrumental case study investigated the level and frequency of use of the web-based communication tools during a full-fledged course delivery at a university that enrols only full-time students. The unit of analysis was the case and the instruments included group interviews, observation anecdotal notes, communication diaries, focus group and a journal/logbook. A mixed qualitative and quantitative research method was used in this research. The study evaluated how the interactivity and not how either the lesson or the WebCT function. The conceptual framework focused on interactivity, features of communication tools that promote interactivity, as well as the domains such as cognition, motivation and learner interface as aspects that influence the use of communication tools. Various web-based tools were used by a sample consisting of a selected small group of IT students who participated in the study. Those communication tools were used to facilitate learning in WebCT. The results showed a total of 145 interactions for the duration of ten sessions. The WebCT communication tools supported either synchronous or asynchronous communication. Communication tools were used to retrieve information and send text-based messages to lecturers and students. Interaction at different levels was evident between student and student, student and lecturer, lecturer and student, lecturer and lecturer, as well as, student and content. In addition to the WebCT communication tools, students used extra web-based communication tools, to facilitate their learning. It was concluded that with continuous advances in information and communication technology and with ever increasing student numbers at resident universities, more tertiary institutions should offer on-line courses. More communication tools should be considered on WebCT to facilitate more interactive learning. / Dissertation (MEd (Curriculum Studies))--University of Pretoria, 2007. / Curriculum Studies / unrestricted
